In a golden rectangle, the sides of the rectangle are as per the golden ratio. The perimeter of the golden rectangle with a width of 15 feet is 79 feet.
<h3>What is a golden rectangle?</h3>
In a golden rectangle, the sides of the rectangle are as per the golden ratio. The rectangle is given the name rectangle because of the fact that the ratio is the golden number 1.618.
In a golden rectangle, the sides of the rectangle are as per the golden ratio. Since the width of the rectangle is 15 feet, therefore, the length of the rectangle will be 1.618 times the width,
Length of the rectangle = 1.618 × 15 feet = 24.27 feet
Now, the perimeter of the rectangle can be written as,
Hence, the perimeter of the golden rectangle with a width of 15 feet is 79 feet.

Answer:
56
Step-by-step explanation:
Complete question:
Z varies jointly with x and y , x=2 and y=2, z=7. Find z when x=4 and y=8 using joint variation . (I need the problem worked out step by step)
If z varies jointly with x, and y, this is expressed as;
z = kxy
If z=7 when x= 2, y= 2
7 = k(2)(2)
7 = 4k
k = 7/4
To get z when x= 4 and y = 8
z = kxy
z =7/4 (4)(8)
z = 7*8
z = 56
Hence the value of z is 56
To find the lateral surface area, use the following formula
la = π × r × s
Given:
π = 3.14
r = 7 ft
s = 13 ft
Solution
Input the numbers to the formula
la = π × r × s
la = 3.14 × 7 × 13
la = 285.74
The lateral surface area of the cone is 285.74 square feet
Answer: Circumference of circle = 27.004 inches
Area of circle = 58.0586 inches²
Step-by-step explanation:
Diameter of circle = 8.6 inches
Pi (
) = 3.14
Circumference of circle (With diameter) = 
d (×diameter)
= 3.14 × 8.6
= 27.004 inches
Area of circle (With diameter) = 
/4
= 3.14 × 8.6 × 8.6 / 4
= 3.14 × 73.96 / 4
= 58.0586 inches²
Answer:
7.25%
Step-by-step explanation:
The item she wants is priced at $20.
The total cost of the souvenir with tax is $21.45.
find:
What tax rate does Lacy pay for the souvenir?
$21.45 = tax ($20) + $20
tax = <u>( $21.45 - $20 )</u>
$20
tax = 0.725 x 100 = 7.25%
therefore, the tax of the souvenir is 7.25%
